Scientists Sloan Digital Sky Survey (STSON) have created a new full-color map of the universe, which includes a quarter of the visible sky. The level of detail is so high that you would need five hundred thousand high-resolution monitors to see it completely. The map consists of more than one billion pixels, assembled together by means of a thorough scan using specialized telescopes located in the state of New Mexico. Held at this week’s annual meeting of the American Astronomical Society in Austin, Texas, STSON researchers announced the results of four separate studies of the new cards, which allow a better understanding of the history of the last six billion years of the universe.
"The map of the universe, created on the basis of observations of the last decade, not only provides an unprecedented view of the distribution of stars, galaxies and quasars, but also allows you to track the evolution of the components of the universe for a long period of cosmic time," - said Donald Schneider, coordinator and co-author STSON all four studies.
Final version of the map STSON was posted on the Internet last year and its time to see more than a million times.
"The way in which the galaxies were distributed in clusters at the moment, has to say two things. First, clustering of galaxies can serve as a measure of the expansion of the universe over time. Secondly, we can use this information for computing the quantity of matter in the universe, including the percentage of normal and black fabrics, as well as neutrinos. "
Among other results, the researchers found a margin of error of only two percent, taking as a basis for the generally accepted cosmological model of the moment, the share of black energy accounted for 73% of the universe.
Amazingly, the map of the universe, which covers an unimaginably large space allowed better acquainted unimaginably small.
The team, led by Roland de Putter of Valenskogo University in Spain, STSON examined in order to determine the maximum possible neutrino masses on the basis of the observable universe. The team was able to determine that the largest neutrino mass corresponding to our universe, is less than one millionth of the mass of the electron, which is much more precisely the methods proposed in particle physics.
Later this year, STSON publish new information, including an extremely accurate distances to many galaxies.
"For each of the millions of galaxies we replace the estimate of the distance to them on a very accurate measurement. Our new card will allow you to put a sharp focus on the universe and see it without interference," - said Antonio Cuesta of Yellen, who participated in all four studies. A more accurate vision of the universe will deepen our understanding of the processes occurring in it and fills it with objects - from the largest to the smallest and.
